南极海冰每日监控（Arctic ROOS）

The new satellite しずく "Shizuku" (GCOM-W1) that carries AMSR2 (the successor of AMSR-E) has been launched successfully on May 18, 2012. It has been delivering data since August 2012. On Januray 25, 2013, the calibrated brightness temperature data have been released to the public. Starting on 26 January 2013, we produce daily sea ice concentration maps from these data.

Note that thorough calibration of the AMSR2/ARTIST Sea Ice (ASI) data has not been finished yet.

As the same frequency (89 GHz) is used as on the AMSR-E instrument and the resolution of AMSR2 is similar, the same ARTIST Sea Ice (ASI) algorithm is applied using the same tie points (calibration constants). The data should be used carefully until full calibration of the AMSR2 / ASI sea ice concentrations has been accomplished

This page presents the AMSR2 sea ice concentrations calculated daily in near real time. The service is part of the GMES project Polar View and of the Arctic Regional Ocean Observing System (Arctic ROOS).

The research for developing, validating and improving the retrieval algorithms was done within the EU Integrated Project DAMOCLES (Developing Arctic Modeling and Observing Capabilites for Long-term Environmental Studies)

The ASI sea ice concentration algorithm used here has been validated in several studies (Spreen et al. 2005,Spreen et al., 2008).
However, no warranty is given for the data presented on these pages.
